A solvent is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution. the most common solvent in everyday life is water. MOst other commonly-used solvents are organic (carbon-containing) chemicals. These are called organic solvents. Solvents usually have a low boilling point and evaporate aesily or can be removed by distillation, leaving the dissolved substance behind.

To distinguish between solutes and solvents are usually present in the greater amount.

Solvent can also be used to extract soluble compounds from a mixture, the most common
example being the brewing of coffe or tea with hot water. Solvents are usually clear and colorless liquids and many have a characteristic odor. The concentration of a solution is the amount of compound that is dissolved in that is soluble in a certain volume of solvent at a specified temperature. Common uses for organic solvents are in dry cleaning(e.g. tetrachioroethylene), ad paint thinners(e.g. toluene, turpentine), as nail polish removers and glue solvents(acetone, methyl acetate, ethyl acetate), in perfumes (ethanol), and in chemical synthesis. The use of inorganic solvents (other than water) is typically limited to research chemistry and some technological processes. in 2005, the worldwide market for solvents had a total volume of around 17.9 million tons, which led to a turnover of about 8 billion euro.
